Dehumidifier upgrade

Hello to all,
New to Ecomodder. Enjoyed what I've read. Great stuff.

My old dehumidifier isn't cutting it.
New dehumidifiers are now judged by Liters per Kwh.
Time for a test.

Before I went to spend new money, I decided to test my old one.
So I ran 3 different tests.
It ran for 2 hours with a Kill a Watt meter attached.
Drained it after a wait. And measured the water with an old kitchen measuring bowl.
Results were averaged. In basement.
2.04 Kwh
1.37 liters= .67 L/Kwh
(liters / Kwh)

Now the new dehumidifiers are rated in L/Kwh.
See attached link:
downloads.energystar.gov/bi/qplist/dehumid_prod_list.pdf

I chose a 1.6L/Kwh 50 pint GE unit. It was a great price. Although a 1.8L/Kwh is a better unit. The extra $50 didn't seem worth it.
And the payback is kinda small .

What was interesting was that the difference of basement cooler temperatures had on output.
While the new GE was averaging 1.56- 1.6 L/Kwh upstairs in warmer temps.
In the basement it was reduced to 1.38. Still, At least a double.
I'm now testing downstairs at different fan speeds. To get max out of it.
But, So far it's much much dryer and hopefully cheaper.
